Embodiment 1

[0018] Preparation of PP superfine fiber melt-blown cotton nonwoven fabric and polytetrafluoroethylene microporous film thermal insulation composite material.

[0019] a. Through the method of melt-blown non-woven fabrics, PP ultra-fine fiber melt-blown cotton non-woven fabrics are first prepared, and the product weight is 30g / m 2 , the fineness range of the fiber is 1-5um, and the average fineness is 4um;

[0020] b. Using melted glue dots, spray ethylene-ethyl acetate (EVA) adhesive evenly onto the outer layer of superfine fiber melt-blown cotton, and compound it with polytetrafluoroethylene microporous film to prepare a windproof , waterproof, moisture-permeable, lightweight and other characteristics of thermal insulation composite materials. Its gram weight of described polytetrafluoroethylene microporous film is 25g / m 2 , the amount per unit area of ​​ethylene-ethyl acetate (EVA) adhesive is about 2g / m 2 .

[0021] The quantitative of this warm-keeping composite mater...

Embodiment 2

[0023] Preparation of PP / PET two-component ultrafine fiber melt-blown cotton nonwoven fabric and polytetrafluoroethylene microporous film thermal insulation composite material.

[0024] a. Through the known melt-blown nonwoven fabric method, firstly prepare PP / PET two-component ultrafine fiber melt-blown cotton nonwoven fabric, and the product has a grammage of 50g / m 2 , the fineness range of the microfiber used is 1-5um, and the average fineness is 4um; the mass ratio of PP / PET two-component microfiber is 30:70;

[0025] b. Then use PA (polyamide) or PES (polyester) powder as a binder, and combine the two-component superfine fiber melt-blown cotton with the polytetrafluoroethylene microporous film in a powder-dusting bonding manner At the same time, it is prepared into a thermal insulation composite material with the characteristics of waterproof, windproof, moisture permeability, and lightness. Its gram weight of described polytetrafluoroethylene microporous film is 15g / m ...

Embodiment 3

[0028] Preparation of PP / PLA two-component microfiber melt-blown cotton and polytetrafluoroethylene microporous film thermal composite material.

[0029] a. Through the known method of melt-blown non-woven fabrics, PP / PLA two-component ultra-fine fiber melt-blown cotton is first prepared, and the product has a grammage of 40g / m 2 , the fineness range of the microfiber used is 1-5um, and the average fineness is 3um; the mass ratio of PP / PLA two-component microfiber is 40:60;

[0030] B, then use ethylene-ethyl acetate (EVA) as adhesive, adopt the mode of dusting to bond described two-component microfiber melt-blown cotton and polytetrafluoroethylene microporous film to be combined together, be prepared into Thermal composite material with waterproof, windproof, moisture-permeable, lightweight and other characteristics. Its gram weight of described polytetrafluoroethylene microporous film is 20g / m 2 , the amount per unit area of ​​ethylene-ethyl acetate (EVA) adhesive is 3g / m ...

Abstract

The invention discloses a method for preparing warming composite material. The invention provided method using a widely-known method of producing cloth melt-blown with non-woven, Producing any one or two of polypropylene, polyethylene glycol terephthalate, polybutylene telephthalate or polylactic acid superfine fiber into superfine fiber then melting and spraying onto the cotton for non-weaving cloth, Denier range of the superfine fiber is one to five Mum, The average denier is three to four Mum, Gram weight of the melt-blown with non-weaving cloth is 30 to 50 gram for every square meters; The using the widely-known adhesive and a composite method to composing the superfine fiber melt-blown non-weaving cloth with polyfluortetraethylene micropore film together, And then the warming composite material is prepared; The gram weight of the polyfluortetraethylene micropore film is 15 to 25 gram for every square meters, Dosage for a certain unit area of the adhesive is two to four gram for square meters. Products produced by using the invention provided method has characteristics of warming, water proofing, wind proofing, ventilating, moisture permeable, comfortable and portable.

Description

technical field [0001] The invention relates to textile heat-retaining material technology, in particular to a preparation method of a novel heat-retaining composite material. The preparation method mainly comprises compounding superfine fiber melt-blown cotton and polytetrafluoroethylene microporous film to prepare a waterproof, windproof, moisture-permeable, light and comfortable thermal insulation material. Background technique [0002] Traditional thermal insulation materials are raw materials such as down, camel hair, wool, cotton, silk floss or chemical fibers. Although these materials have good thermal performance, but due to the limitations of texture and structural characteristics, they are either too fluffy, or hardened, not resistant to insects and mildew, inconvenient to wash, poor in moisture absorption and air permeability, and inconvenient in sewing and processing, etc. shortcoming. Ultrafine fiber melt-blown cotton is a fiber material made by melt-blown non...
